The ancient Greeks considered a rainbow to be a path linking the heavens and earth. Scientists consider a rainbow to be a meteorological phenomenon that causes a spectrum of light to appear in the sky when the sun shines onto droplets of moisture in the atmosphere. I just think they're pretty.

This is a double rainbow that formed at sunrise over a forest of dwarf lenga trees near Laguna Torre, Los Glaciares National Park, Patagonia, Argentina. To read more about my Patagonia adventures, check out Chapter One and Chapter Two of my Patagonia Photo Journal. [link]

I didn't know that about the Greeks. Interesting to know! Thank goodness for cameras or else we would never be able to share this with others, the way you've done for us. It's too bad I hadn't come across this photo or your tutorial earlier, because it would have helped with an earlier capture of mine. Unfortunately, a vague rainbow came out on film...

you should seriously consider going, its an magical and amazing place. the problem is that people there are modernizing so you should hurry up. the real traditions are going away but the landscapes are still there and they are AMAZING.take a look here are some pictures about the place:[link]
